Is my dog's head shaking and pain due to an ear infection?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 3 years and 4 months old | 80 lbs

Last night, my dog suddenly started whining and shaking his head violently. When he stopped, he was holding his head tilted to one side. He's obviously in pain. He keeps licking the inside of his mouth, like he just ate peanut butter, but he will not let me look in his mouth and keeps it tightly clamped shut. He is now being quite lethargic. I was thinking a neck muscle strain, or that he swallowed something that stuck in his throat. Any thoughts please?

It's probably an ear infection, often it cannot be seen from the outside but head shaking is the main symptom. Ear infections are very common in dogs, it is usually caused by either yeast or bacterial disease. the treatment is usually simple and straightforward, you will have to take Merlin to the vet and get the ears checked, then a prescription ear drops will be prescribed according to the infectious agent.

    This is a sign of an ear infection. In dogs, ear infections can be caused by yeast or bacteria. Any ear problem needs to be checked out by a vet promptly as leaving it untreated can lead to hearing loss. I'd take May into the vet in the morning to get this diagnosed and treated. I hope this helps!

    I would be concerned that Roots has an ear infection. Shaking the head is a classic sign of it. Ear infections in dogs can be caused by ear mites, yeast, or bacteria. I would make an appointment with his vet first thing in the morning. The vet can diagnose if he does have an ear infection, and can treat him for it. Best of luck, I hope this helps!

    Head shaking is usually consistent with an inner ear infection. He may also be nauseous or just very uncomfortable. It is important to have him seen by a veterinarian to determine the cause.
